游戏运行时自动执行方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RuntimeInitializeOnLoadMethodTest
{
    // 场景载入后游戏开始运行时触发
    [RuntimeInitializeOnLoadMethod]
    static void OnRuntimeMethodLoad()
    {
        Debug.Log("OnRuntimeMethodLoad");
    }

    // 场景载入后游戏开始运行时触发
    [RuntimeInitializeOnLoadMethod]
    static void OnSecondRuntimeMethodLoad()
    {
        Debug.Log("OnSecondRuntimeMethodLoad");
    }
}

----------------------------------------------------------------------------------------------------

[ExecuteInEditMode] //当Editor不运行时Test脚本也能执行
public class Test : MonoBehaviour { }

给脚本加帮助文档URL
